Do your legs feel stubbornly swollen and weighed down? Do you feel pain or tingles when you try to touch them? If so, you might have lymphedema, a frustrating condition that affects as many as 10 million Americans, and 250 million people worldwide (1).
Lymphedema happens when your lymphatic system doesn’t work as it’s supposed to (2). A properly functioning lymphatic system helps your body transport and eliminate toxins, waste, and immune cells. When it doesn’t, fluid may build up in the body, especially in your legs or arms.
Some people are born with genetic conditions or lymphatic issues that lead to lymphedema, like Meige disease or Milroy disease (3). Lymphedema caused by this is called primary lymphedema (4).
The more common form of the condition is secondary lymphedema, which develops as a result of a health condition, injury, surgery, or treatment. One of the most common causes of secondary lymphedema is cancer treatment, including the removal of lymph nodes and radiation therapy. It’s especially associated with breast cancer treatment that includes a mastectomy. Secondary lymphedema can also be caused by infections, cardiovascular diseases, certain injuries, and inflammatory conditions like eczema or rheumatoid arthritis.
Lymphedema commonly strikes the legs, and when it does, it can cause pain, swelling, and even mobility issues.
